Phenomenological models of high-energy hadronic collisions (e.g. EPOS-LHC, QGSJet, SIBYLL, DPMJET) used in air-shower simulations to extrapolate particle production beyond collider energies. Claims about their predictions, tuning to LHC data, inter-model comparisons, or their effect on air-shower observables belong here.
Auger hybrid data are best described when hadronic model predictions are shifted to deeper shower maxima and larger ground-level hadronic signals
